Does removing the background .PNG files (add to the Memory
OPTIONS -> MEMORY), as the maximum I have ever seen is around 38mb.
When I removed and restarted the phone, didn't seem to make any difference..

I have Weatherbug, Blackberry Pro 3 Theme, all the standard blackberry apps,Viigo, FacebookmRDM+, QuickPull, I Love Blackberry..
NOT: AIM, Googletalk and Yahoo Talk.
With all applications CLOSED I have around 28mb to 30mb after a few hours.
Just curious as to how some people report 48mb.
I find .151 to be the best OS so far, with everything working well together.

Thanks agian for your comments

The apps that I put in bold are known for a memory leak. Some of them are big in size (1mb +), so that's most likely where your memory goes.
